OSCAR M. SHANNON, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHICAGO LAUNDRY DRYER COMPANY, OF SAME PLACE.

WATER-HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 429,799, dated June 10, 1890.

A Application filed April 16, 1889- Serial No. 307,455. (No model.)

To all whom it may concern.- 1 Be it known that I, OSCAR M. SHANNON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water-Heating Devices; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being'had to the accompanying draw ings, and to the letters of reference marked thereon, which form a part of this specification. a

This invention has for its primary object to provide a more eflective construction in water-heating apparatus in which gas or vapor fuel is employed as the heating agency.

It also has for its object to produce a combination of a water-heating apparatus employing gas as a fuel with a kitchen-range boiler or tank of present universal construction, by which the apparatus may be applied to such boiler ortank without taking up more lateral space in the room than is occupied by the boiler itself.

The nature of the invention will be best understood from the following description of the accompanying drawings and from the appended claims.

In said drawings, Figure l is a horizontal section of one form of the heater in the line 1 l of Fig. 2. Fig. 2 is a vertical section in the line 2 2 of Fig. 1. Fig. 3 is a vertical section in the line 3 3 of Fig. 2. Fig. lpresents a side view of the water-heater with a gasburner arranged-beneathit and with a kitchenboiler arranged above it, the connections being made with the boiler by means of pipes adapted to give the desired circulation of the water of the boiler through the heater. Fig.

5 is a horizontal section of another form of water-heater intended to be used in connection with a second similar heater, so as to form what I term a twin or duplex heater, section being taken on the line 5 5 of Fig. 7. Fig. 6 is a vertical section of one of the twin heaters in the line 6 6 of Fig. 5. Fig. 7 is a side View of one of the twin heaters and a section of the pipe connecting the two similar heaters in the line 7 7 of Fig. 5, looking in the direction of the arrow. Fig. Sis a side view of the duplex heater connected with a kitchen-boiler in a suitable manner to give I circulation of the water of the boiler through the heater, and in connection also with two separate gas -burners arranged one under each heater of the duplex device.

The water-heater in its application to a radiator is shown in certain figures of another application for patentto wit, Serial No. 329,131, pending simultaneously herewith.

' In the present drawings, A represents the water-heater as a whole. This water-heater is a flat or shallow chamber, having an inlet and an outlet and a sinuous passage from one to the other through which the water flows in the operation of heating it. As illustrated, the heater A is composed of two plates A and A of which the upper plate A is of castiron provided with a depending rim a, having an outwardly-turned flange a at its free edge, and also provided with a series'of interior flanges or partial partitions a a a, forming deflectors by which a desired sinuosity of the water-course is produced. The flange or partition a as here shown, extends from the rim a at a point between the inlet a and outlet a to a point near the opposite side of the structure, and the flanges a branch from the flange a but, like the. latter, terminate at a distance from the rim a. The flanges a proceed inwardly from the rim between the flanges a and terminate at a suitable distance 'from the flange a Other arrangements of deflecting plates or devices may obviously be employed with the same result and'without departure from my invention.

The bottom plate A is of sheet metal, and in the construction shown is secured to the plate A by having its edge folded over the flange a and soldered or otherwise securely fastened thereto so tightly as to prevent leakage. In use the bottom plate A is directly over the flames of the burner, and byreason of its slight thickness promptly transmits the heat of the flames to the water passing over it. The inlet a and the outlet a are formed ually inclined from one of these points to the other.

B represents a kitchen-range boileror tank. In the application of the heater to such a boiler or tank the inlet-opening of the heater A is connected by a suitable pipe with the lower orifice of the boiler B, which is usually in the bottom, and is so indicated in the drawings. The other or outlet opening of the heater is similarly connected with the tank at a higher point. The pipes making these connections are lettered C and C, respectively, and through said pipes and the heater A the water of the tank is circulated by the application of heat to said heaterA.

C is a branch adapted to connect with the inlet of a range water-front or with a tap, or both, by which the contents of the tank B may be drawn off.

The burner I) is supported beneath the heater A so that the flames proceeding therefrom act etfectively upon the water in the heater through the thin sheet-metal bottom plate A As a preferred construction and as a special feature of improvement the burner is shown secured in the proper position beneath the heater by attachment to the latter instead of being separate or separately supported. This construction enables the heater and burner to be handled as an integrality or single apparatus, with certainty that they will occupy their proper relations when put to use independently of the judgment of the workman who sets it up. The means here shown for thus connecting the heater and burner are a series of suspendingbars (Z d, bolted or riveted to the margin of the burner and hooked at their upper ends over the marginal flange of the heater. The burner may of course be otherwise connected with the heater, and the connection may be detachable or permanent, as desired.

In connecting the heating apparatus with a kitchen tank or boiler it is also a preferred construction and it is a special feature of improvement to place the heater and burner beneath the tank. It thus requires no additional space in the room, while the waste heat from the burner and heater rises against the bottom of the tank and further contributes to heating its contents. lVith this arrangement in view the single heater and burner is adapted to enter the space between the branched arms of the ordinary standard E, so that the application of the device to tanks already set up or in connection with such standards will be practicable.

In the case of the double or twin form of the device shown in Figs. 5 to 8 the two similar heaters A are placed one on each side of the plane of the stamlard-arms, as indicated particularly in Fig. 8. A single coldwater orinlet pipe 0 in this instance descends straight from the central bottom opening in the tank into a cross-pipe c, which connects with both heaters, and from the end of each heater a delivery-pipe C passes to a common connection 0 with the hot-water inlet of the tank.

The tank supplied with either form of gasheating device may be also connected with the water-front of a range or stove, so that both the range and the gas-heater may be used and the contents of the tank may be heated more rapidly than by either heater alone. In that case the pipe 0 may represent the connection with the inlet 01": the water-front of the range, the outlet of the Waterfront being connected with the pipe 0 or with the tank by a separate opening into the latter.

I claim as my invention 1. In a water-heating apparatus, the combination, with a gas or vapor burner, of a Waterchamber placed over the burner, which chamber has its upper part of cast metal and its bottom of sheet metal, and is provided with an inlet and outlet through the cast Walls thereof and a sinuous passage between the inlet and outlet.

2. The combination, with a range boiler or tank and a bifurcated standard supporting the tank, of a water-heating apparatus comprising a water chamber provided with a sheet-metal bottom and a subjacent gas or vapor burner, both located beneath the tank, said water-chamber havingits inlet connected with the central bottom orifice of the tank and its outlet in communication with the tank interior at a higher point.

3. The combination, with a range boiler or tank, of a duplex water-heater consisting of two separate water-chambers, each having an independent burner beneath it and both located beneath the boiler, said Water-chambers being connected with a single pipe which leads from the central bottom orifice of the tank, and each having its outlet in communication with the interior of the tank at a point above its bottom.

4. A water-heater for use with flames of gas or vapor and adapted for connection with a vessel the contents of which are to be heated, composed of a casting having a marginal flange which is outwardly turned at its free edge and a sheet-metal bottom plate secured to said flange, the chamber so formed having an inlet and an outlet and a sinuous passage from one to the other.

In testimony that I claim the foregoing as my invention I alliX my signature in presence of two witnesses.

OSCAR M. SHANNON.
